MIG feed roller groove



Looks like I'll have to make a new feed roller for my MIG as it now
slips and looks obviously worn - obsolete machine no spares available.

What groove shape should I aim for - it is now rounded as you'd
expect, but are they 'Vee' shaped, square edged or round when new?

Machine is BOX Autolynx 2 if anyone has a handful of rollers <G>
